REINHOLD G. MARQUARDT, OF MILWAUKEE, WISCONSIN.

WOVEN-WIRE :MATTE/ESS.

Application filed November 9, 15308.

Specification of Letters Eatent.

To all whom it may concern.'

Be it known that I, RniNHoLn G. MAR- QUARDT, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Vv'isconsin, have invented new and useful Improvements in Woven-lvl?ire Mattresses, of which the following is a specilication.

My invention relates to improvements in woven wire mattresses, and it pertains more specially among other things to the device by which the following` objects are accomplished: lst. By which the slack of thev mattress between the respective end bars of its supporting frame is taken up from time to time as the ,mattress becomes stretched without moving said end bars 2nd. by which the respective sides of the mattress are prevented from converging or being drawn inwardly toward the longitudinal center of the mattress by downward pressure upon its upper surface; and 3rd. by which one side of the mattress may be put under greater or less tension than the other and so adjusted that it will remain level when used by a light and heavy person.

The construction of my invention is further eXplained by reference to the accompanying drawings, in which- Figure l represents a plan view thereof. Fig. 2 is also a plan view of a modilied form of one end ofthe mattress only, in which the turn buckles are dispensed with and the tension cables are tightened with an ordinary nut, having screw threaded bearing thereon.

Like parts are identified by the same reference figures throughout both views.

l represents the longitudinal members of the mattress frame.

2, 2, are the end members.

3 represents a woven wire mattress of ordinary construction, which is connected at its respective ends with the ends of the frame. The mattress 3 is preferably provided at its respective sides with cables fl, 1i. The respective sides of the mattress are provided with tension cables 5, 5, and 6, 6. @ne of the ends of the respective cables 5 and 6 are permanently connected with one of the end members 2 of the frame, while the other ends of said cables are connected with the opposite end member of the frame by turn buckles 7 and screw threaded connecting rods 8, 8. One end of the rods 8 are rigidly connected with the end of one of the members 2, while their opposite ends are provided with screw threads for the reception of the screw threaded ends of the turn buckles 7. rihe opposite ends of the turn buckles 7 are provided with longitudinal apertures for the ends of the tension cables 5 and 6, which cables are inserted in said apertures and up set in such a manner as to permit the turn buckles to turn upon the end of said cables 5 and 6, as their opposite ends operate on the screw threaded bearings of the rods 8. Thus it is obvious that by turning said turn buckles forwardly and backwardly upon their screw threaded bearings, the tension of the cables 5 and 6 may be increased or diminished.

The central pertions of the cables 5 and (i are connected with the mattress 8 by the loops 9, 9, and transversely arranged rods 10. rlhe outer ends of the rods l0 are respectively connected with the cable Ll of the mattress, whereby as the tension of said cables is increased, the central portion of the mattress will be forced outwardly until the mattress is given the desired tension. The fastening loops 9 may be formed integrally with or independently of the transversely arranged rods l0 and said loops serve to connect both the tension cables 5 and 6, as well as the rods l() with the mattress.

ln the modiiied form shown in Fig. 2, the turn buckles 7 are dispensed with and the ends ofthe cables il extend through the end rails of the mattress and are provided with screw threaded bearings for the reception of the nuts 12, whereby it will be understood that as said nuts are turned down on the ends of said cables against the surface of the end members 2, said cables will be tightened, while by a reverse movement, they will be loosened. it will also be understood that by the device shown, the tension of either side of the mattress may be increased or diminished without increasing or diminishing the tension of the other side, whereby the same is adjusted as stated., to correspond with the weights of different persons, and whereby the mattress may be maintained in a level position under different pressures. It will also be understood that the tension of the mattress may with my device be increased or diminished without changing the relative position of the end bars to the side bars of the frame.

Having thus described my invention what l claim as new and desire to secure by Letters Patent, is-

i. In a device for manually increasing and diminishing the tension'otl a woven wire mattress by forcing its central portions outwardly at right angles to its longitudinal center, the combination of a mattress frame having stationary end members, a woven wire mattress permanently attached at its respective ends to the end members ci the frame, a plurality of tension cables respectively connected at their ends to the en d frame members near the corners of said frame and extending from thence inwardly toward the longitudinal center of the frame, a plurality of transversely arranged rods respectively connected at one end with the central portion oli said tension cables and mattress, and extending from thence cutwardly and connected with the edge and at intermediate points with said mattress, and means for increasing and diminishing the tension of said cable.

2. In a device for manually increasing and diminishing the tension ol' a woven wire mattress by forcing its central portions outwardly at right angles to its longitudinal center, the combination ol a mattress frame having stationary end members, a woven wire mattress permanently attached at its respective ends to the end members o1 the frame, a plurality of tension cables respectively connected at their ends to the end frame members near the corners of said frame and extending from thence inwardly toward the longitudinal center of the frame, a plurality of transversely arranged rods respectively connected at one end with the central portion of said tension. cables and mattress, and extending from thence outwardly and connected with the edge and at intermediate points with said mattress, and turn buckles connected with said tension cables for increasing and diminishing theirtension and the tension of the mattress.

3. In a device for manually increasing and diminishing the tension of a woven wire mattress by forcing its eentralportions outwardly at right angles to its longitudinal center, the combination of a mattress frame having stationary end members, a woven wire mattress permanently attached at its respective ends to the end members of the lran'ie, a plurality of tension cables located upon the respective sides oi the longitudinal center ot said mattress and respectively connected at their ends to the end trame members near the corners of said frame and eX- tending from thence inwardly toward the longitudinal center cf the frame, a plurality ci transversely arrai'iged rods located upon the respective sides oi the longitudinal center of the mattress, and respectively connected at one end with the central portion of said tensien/ cables and mattress, and eX- tcnding from thence outwardly and connected with the edge`and at intermediate points with said mattress, and turn bucl-:les connected with said tension cables for increasing and diminishing their tension and the tension of th mattress, all substantially as and for the purpose specified.
